UNITED STATES PATE ROBERT, BERTRAM' BEST, OF KALAMAZOO, MICHIGAN EMULSIFYING OR MIXING APPARATUS.

Application filed August 25, 1924. Serial No. 734,143.

To all whom it may concern:

Be itknown that I, ROBERT BERTRAM BEST, a subject of the King of Great Britain, residing at the city and county of Kalamazoo, State of Michigan, have invented certain new and useful Improvements in Emulsifying or Mixing Apparatus, of which the following is a specification.

This invention relates to improvements in an emulsifying or mixing apparatus.

My improved emulsifying or mixing apparatus is especially designed by me for emulsifying or preparing size for use in paper making, although it is adapted for use in other relations where it is desired to produce an emulsion or mix some material with water.

The main object of this invention is to provide an improved apparatus of the class described in which the size or other material is eifectively emulsified or mixed with the desired proportions of water.

A further object is to provide an improved apparatus of the class described which is automatic in its operation.

Objects relating to details and economies of construction and operation will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claims. A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing, forming a part of this application, in which:

Fig. I is a side elevation of an apparatus embodying the features of my invention, various parts being shown in conventional form for convenience in illustration.

Fig. II is a longitudinal central section through the ejector by means of which the size or other material and water are proportioned and mixed.

' Fig. III is a detail longitudinal section of a mechanical mixing device which I preferably employ.

Fig. IV is a vertical section through the apparatus for regulating the pressure and temperature of the water delivered.- In the drawing similar reference characters refer to similar parts throughout the several views. v

Referring to the drawing, 1 represents a water supply pipe and 2 a steam supply pipe. The emulsion or storage tank 3 is preferably connected to the water supply pipe by the branch 4 provided with a valve 5.

The size tank 6 has a heating coil 7 therein connected to the steam supply by the pipe 8 having a valve 9. The water supply pipe 1 delivers to the tank 10, a valve '11 being provided in the supply pipe. The exhaust pipe 12 of the coil 7 delivers to the water tank, a valve 13 being provided for this exhaust pipe.

I provide an apparatus designated generally by the numeral 14 for regulating the temperature and pressure of the water delivered through the discharge pipe 15. This device is connected to the steam supply pipe by the connection 17 and to the tank by the pipes 18 and 19.

t The device 14 shown in section in Fig. IV

is an automatically actuated inspirator by means of which the pressure and the temperature of the water delivered through the discharge passage 14 is regulated. In general this comprises a casing 40 having a main cone 41 and a supplemental or aux-' iliary cone 42 having steam nozzles 43 and 44, respectively, operatively associated therewith. The nozzle 43 is controlled by the valve 45, this valve having a lost motion connection to the main steam valve 46, the stem 47 of which is connected to the lever 48. The lever is shown by full lines in position to open the valve 46 thus admitting steam to the nozzle 44. A further throw of thevlever to the position indicated by the outer dotted lines will also open the valve 45. The operation of inspirators of this type is well understood.

In the pipe 15, I interpose an ejector consisting of the chambered body 20 connected by the valved connection 21 to the tank 6; The mixing cone 22 is threaded into the rear nipple 24 of the body and is provided with a collar 25 engaging the end of the nipple, thereby positioning the inner end of the cone or mixing tube within the chamber. The

. water nozzle or cone 26 hasa flange or collar 27 at its outer end which engages in the seat 28 in the nipple 29 at the front end of the body. This collar 27, coacting with the seat,

determines the position of the nozzle or water cone relative to the mixing cone. The coupling 30 being threaded upon the nipple 29, clamps the water nozzle in position. The

advantage of this is that when handling rosin size, there is a tendency to clog and these parts may be disassembled and reassembled by an unskilled workman without varying their position as is likely to occur where parts are threaded together for adjustment,the matter of proper proportions 'of water and the size being of great importance. Thisenables the adjustment by a person having knowledge of the requirements in the first instance as by grinding off the end of the water nozzle or the collar to secure the proper proportions for the particular emulsion desired. Thereafter, it is merely a matter of assembling or disassembling the parts and the mill operators cannot get the parts out of adjustment. The pressure and temperature of the water being automatically controlled, the result is that a very uniform emulsion or mixture is secured. I

I also preferably provide in this connection a mixing turbine designated generally by the humeral 3l.consisting of a pair of body members 32 and 83 threaded together and adapted to be interposed in the pipe 15.-

A spider 34" carrying the shaft 35: for the spiral mixing blade 36 is clamped between theends of the. members 82 and 33 and a shouldered sleeve 37 threaded thereon. This turbine serves to' further agitate and mix the materials so that when discharged to the tank 3 the same is thoroughly emulsified.

I have illustrated my improvements mainly in conventional form but it is believed that this will enable those skilled in the art to which myinvention relates to embody or-adapt the same as may be desired.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:
